SPECIFICATION'forming part of Letters Patent No. 480,522, dated August9, 1892.

Application filed September 18, 1891. Serial No. 406.088. (No model.)

To all whom it may concern:

Be it known that I, DONALD SKEKEL, of Georgetown, in the county ofDemerara, Brit'- ish Guiana, have invented a new and IniprovedCane-Mill, of which the following is a full, clear, and exactdescription.

The invention relates to improvements in three-roller sugar-cane mills;and its objectis to provide a new and improved cane-mill which is simpleand durable in construction, very effective in operation, and arrangedto utilize the crushing power to the greatest advantage and withoutinjuring the head-stocks.

The invention consists of certain parts and details andcombinations ofthe same, as will be fully described hereinafter, and then pointed ontin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a sectional side elevation of the improvement. Fig. 2 is asectional plan View of the same. Fig. 3 is an end elevation of the samewith parts in section, and Fig. 4 is an enlarged face view of the guidefor the corrugated turning-roller.

The improved cane-mill is provided with three parallel rollers A, B, andC, journaled in suitable bearings D, E, and F, respectively, heldadjustably in the head-stocks G and G. The rollers A and B are the twotop rollers and are arranged in a horizontal plane, as is plainly shownin the drawings.- The third roller C is located directly below the toproller A and forms with the latter the front or entrance rollers betweenwhich the cane is passed in order to crush the same.

In order to relieve the head-stocks G and G of the strain incident tothe crushing of the cane, sets of horizontal bolts H are provided foreach head-stock, the said bolts being U-shaped and extendinghorizontally in line with the bearings D and E for the top rollers A andB, respectively. The bolts H pass at their ends through the caps G2, arranged at the rear ends of the stocks, the nuts of the said boltsscrewing against the said caps, as is plainly shown in the drawings. Asecond set of bolts I is arranged for each head-stock and ext-endsvertically at the sides 4 of the bearings D and F, serving to take upthe strain incident to the crushing of the cane between the two rollersA and C, it being understood that the other bolts H take up the strainincident to the crushing of the cane between the rollers A and B. Theupper ends of the bolts I pass through caps G3, against which abut thenuts of the said bolts.

In order to guide the cane upward between the top rollers A and B afterthe cane has left the entrance-rollers A and C, the corrugated roller Jis provided, located in the rear of the entrance-rollers A and C andbelow the top rollersA and B. rlhe roller J is journaled in suitablebearings K, held in the headstocks G and G', so that the cane afterleaving the front rollers A and C is pushed upward by the corrugatedroller J to pass be tween the rollers A and B to undergo the l iinalcrushing.

It is understood that the several rollers A, B, and C are geared witheach other to rotate in unison. The roller J is also geared with thesaid crushing-rollers and in such relative proportion that the speed ofthe roller is equal to the surface speed ot' the crushing-rollers.

ln order to prevent the cane from passing to the bearings K of thecorrugated roller J, guides L are provided, each bolted inside of one ofthe head-stocks, as is plainly illustrated in Figs. 3 and 4. Each guideL is formed with a segmental projection L', eX- tending over the end otthe corrugated roller J, as is plainly illustrated in Figs. 3 and 4. Thetop surface of this projection L is inclined upward and outward toprevent jamming of the cane. The under side of each guide L is formedwith a semicircular offset L2, passing over part of the shaft of theroller J in front of its bearing K to prevent the cane from passing tothe said bearing. The bearings F for the rollers C extend to the frontside head-stocks G and G and can be conveniently removed to permit ofremoving the lower entrance-roller C without taking the machine apart.

It will be seen that by arranging the crushing-rollers in the mannerdescribed the juice pressed out of the cane is not liable to return intothe crushed cane, as the said juice passes down over the roller J to asuit-able recepta- Lis IOO

cle located in the lower part of the machine. Thus the crushed canewhich iinally passes upward from the rollers A and B is comparativelyfree from juice.

The roller J on account of being corrugated readily turns the caneupward to guide it to and between the rollers A and B.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A cane-mill provided with three crushing-rollers,of which two are the top rollers and are arranged in a horizontal plane,while the third is located under the first top roller and forms with thelatter the front or entrance rollers for the cane to be crushed, acorrugated turning-roller arranged in the rear of the front 0r entrancerollers and below the top rollers, and the guides L, formed with upwardand outward inclined integral projections L', extending over the ends ofthe corrugated roller, and with semicircular olsets L2, projectingbetween the ends of said roller and its bearings, substantially as shownand described.

2. In a cane-mill, the combination, with the head-stocks, of threecrushing-rollers journaled in the said head-stocks and of which two arethe top rollers arranged in a horizon-
